Win Two 'Greenwild' Books

We're giving you the chance to win two of the magical Greenwild stories, featuring fabulous fantasy with an environmental twist!

In Greenwild: The World Behind the Door - the overall winner of the Waterstones Children's Book Prize - Daisy Thistledown escapes from boarding school on a mission to find her missing mother.

On her quest, she discovers a hidden door to another world - the Greenwild, bursting with magic and filled with plants. But before long, she finds herself confronting a dangerous presence that threatens green magic on both sides of the door...

And in Greenwild: The City Beyond the Sea, Daisy smuggles herself on board an expedition to the Amazon, only to find herself in danger on the high seas. Her only hope is to find the legendary Iffenwild, a city hidden below the depths - but a strange, wild magic is stirring beneath the waves.
